  • 简介:one-bead-one-compound(OBOC)组合的肽图书馆是一个强大的工具识别ligand和受体相互作用。这里,我们使用了OBOC图书馆技术识别对主要贝壳变应原tropomyosin的免疫球蛋白E(IgE)epitopes特定的mimotopes。有8-12氨基酸残余的OBOC肽图书馆为tropomyosin的IgEmimotopes与贝壳过敏症从病人与浆液样品被屏蔽。25mimotopes从屏蔽被识别,他们到tropomyosin特定的IgE的有约束力的反应被肽ELISA证实。这些mimotopes能基于顺序相同被划分成七簇,并且由聚类的mimotopes的EpiSearch印射的epitope被执行描绘并且证实mimotopes的有效性。五从六预言的epitopes被发现与tropomyosin的以前识别的epitopes重叠。为了推进,证实mimotopes的模仿潜力,BALB/c老鼠被使免疫,mimotopes结合了到锁眼恋栈者hemocyanin和assayed让他们的能力导致tropomyosin特定的抗体。那收到的mimotope免疫被发现有tropomyosin特定的免疫球蛋白G的提高的水平的BALB/c老鼠,然而并非收到了无关的mimotope的老鼠。这研究用整个sera开创OBOC图书馆的成功的申请屏蔽并且识别多重虾变应原mimotopes并且验证他们在vitro使用的模仿潜力,在vivo,并且在silico方法。
